Description
The Cross Armory +0 Magazine Extension keeps your magazine capacity the same while improving what matters most: your grip and control. Built from aircraft-grade aluminum, it weighs just 4 ounces and maintains the slimmest profile available for flush carry applications.
What Makes the Cross Armory +0 Stand Out
Most magazine extensions sacrifice practical grip for aesthetics. Cross engineered this one with 90-degree angled slots that give you secure purchase even with wet hands or gloves. The scalloped design looks clean but functions hard, making reloads faster when you actually need them. Installation is straightforward using a single screw with thread-lock, no complex retention systems to overthink.
Precision Machining, Built to Drop
This extension is machined from a solid block of aluminum rather than stamped or cast, which means consistent quality and guaranteed smooth magazine drops when empty. The weight distribution is intentional, adding just enough heft to stabilize the magazine without printing under your shirt or creating unnecessary bulk in your carry rig.
Compatible Across Generations
Fits Glock 17, 22, and 31 pistols from Generation 1 through Generation 5. Works with all modern magwells and standard holsters designed for stock-profile magazines. The silver anodized finish resists corrosion while maintaining a professional appearance.

Frequently Asked Questions
Will this Cross Armory extension fit my current holster?
Yes. The +0 extension maintains the lowest profile available, so it works with standard holsters designed for stock Glock magazines. The compact shape is specifically engineered to fit all magwells and holsters without requiring a larger or specialized carry rig.
How is installation different from other magazine extensions?
Cross kept it simple: just a single screw with thread-lock instead of complex retention systems. You can install this in minutes without special tools. The simplicity makes it more reliable and less prone to issues down the road.
Does the +0 extension actually add weight to my magazine?
It does add 4 ounces, which provides intentional weight distribution that helps stabilize the magazine and improves its feel in hand. This matters more than you'd think when you're managing reloads under pressure or working with gloves.
What makes the grip better on this extension compared to stock basepads?
The slots feature engineered 90-degree angled ledges at the front and sides designed to give you solid purchase with wet hands or gloves. Most extensions have weak or no real grip at all, but this one was built specifically for the kind of control you need when it counts.
